User Interface Resizing (missing from View menu)

I am trying to resize the interface in Write because I am having many problems seeing the spellcheck options and text. As suggested in many places I went to Tools - Options - Libre Office - View, but there is no option to scale the interface itself (only icons). The word “scale” doesn’t even appear in any of the options. I have fouynd the Expert configuration but I have no which option to change. Any help is much appreciated!

The operating system controls app and app text size normally. In Windows 11, Start menu > Settings > System > Display and under Scale & Layout change the value in Scale. Other operating systems will have similar options I believe
